KBS3-2 Coax Camera to Digital Video Converter Unit

The Alpha Communications® / S.T.R.™ KBS3-2 coax camera to digital video converter unit is used only with the S.T.R.™ 2-wire QwikBUS™ series video-intercom systems, when a customer wishes to use their own separate CCTV camera and camera power supply. The KBS3-2 is used to convert the video data signal from customer's camera's conventional NTSC coax signal, to a digital signal to be sent to the 2-wire QwikBUS™ video monitor(s).

The KBS3-2 gets its power from the TT33-2 (or TTE33-2) speaker / microphone module and does not require a separate power supply.

Each camera connected to the QwikBUS™ series video-intercom system, requires its own separate power supply (provided by the installer).
